My A3 slowlllllly loses coolant. Not enough for me to worry about. Topped it off once and it’s between full and low now after putting 25k on it since I’ve owned it.

I'm bringing my car in Wednesday for the same issue, 36k miles. It has always dropped in level since I've owned it but now when hot I smell coolant at the front of the engine. I always smelled a faint amount near the turbo but now it's really strong. No visible leaks.

I also have an oil leak at the PCV so we'll see if that's covered. I had my advisor write up a ticket already and got it in under the BtoB warranty, 35,930 miles. :) It's probably powertrain and I've still got the CPO warranty but just in case.

I’m at 25k miles on a 2016 I haven’t touched the coolant. I remember it being much higher than that. Car is completely cold right now if that makes any difference.

Replaced my thermostat housing last month. The problem is NOT that it is plastic, nor is it an issue of a poor mating to the engine...it simply fails internally and leaks from the lower front section (not the mating surface). So while the USP cast housing might not leak, it's probably just designed better internally

I personally haven't seen/read about anyone using the cast housing. You can buy the cast for about $100 more than the OEM, so I guess it's worth trying.
Ohhh thats a thing? Because I need a permanent fix too had my second thermostat housing garbage under warranty replaced again seems to be a reoccurring thing every 3 months of 2020 on my 1.8T vw golf 2017. So can you provide link I want to change mine asap this is complete bs as I am at 75.5 k km and warranty ends 80k so i want to never ever visit dealership ever again and have my sht sorted.
